imagine there is a positive pt charge somewhere in space. so the E field due to this pt charge, falls off with distance. now, i place a conducting rod parallel to the field some distance away, such that one end of the rod is at V_A and another end is V_B (where V_A > V_B) we also know that there can be no net E-field in a conductor. so potential must be constant throughout a conductor. my question is. what is the potential?? V_A or V_B? or what?
